Abstract
PURPOSE: To switch temporarily current set value of degree for preventing interruption of DC current to output value of a current setting instrument for producing the current set value upon reception of a tidal alteration command by providing the instrument in the respective control circuits at both ends.
CONSTITUTION: When a tidal alteration changeover switch 10 is switched from a converter 2 to converter 2', one-shot multivibrators 18 and 16' operate for predetermined time to then close switches 15, 15'. Thus, set value Idpo is applied to maximum value selecting circuits 14, 14', respectively. Normal current and minimum current values determining set value Idpm is applied to the circuits 14, 14'. The value Rdpm is 10% of rated current value, and the value Idpo approx. 20%. Accordingly, if Idp≥Idpo, the current control at tidal alteration time is set by a current setting instrument 11. If Idp<Idpo, the tidal alteration time is so operated that the current set value Idpo has priority.
